Fukushima Daiichi Contaminated Water Leakage to Sea
Tokyo Electric Power Co. (TEPCO), the owner of the Fukushima Daiichi nuclear power plant, announced that it had completed in early August an underground wall in the premises near the Pacific Ocean to prevent leakage of radioactively contaminated water to the sea.
Experts concerned recently pointed that some contaminated water was still flowing into the sea, even though it was more than two years after the start of the Fukushima Daiichi accident. That is why TEPCO started to build this wall this July.
The wall, 100 meters wide and 16 meters deep, was constructed by infusing liquid glass into the ground. But there left is a gap of 1.8 meters between the top of the wall to the surface of the ground.
On the other hand, there is a trench in the ground under buildings housing crippled nuclear reactors. In it, radioactively contaminated water is kept. But groundwater also flows into this trench. Accordingly, an increased amount of contaminated water flows to the underground wall. Very unluckily the depth of this water flow is 1.2 meters from the surface of the ground. Consequently the radioactively spoiled water runs over the wall to the Pacific Ocean eventually.
In this way 300 tons of problematic water flows into the sea every day from the Fukushima Daiichi nuclear plant which is still under recovery work after its drastic destruction in the wake of huge tsunamis triggered by an M9.0 earthquake of March 11, 2011.
(What is worse, it is also recently that TEPCO could correctly measure how much water is leaking to the sea. This amount 300 tons gave a great shock to the society when it was made public.)
TEPCO plans to abolish this nuclear power plant, taking probably scores of years. But this leakage has apparently made the situation more complicated.
For example, in response to this situation, fishermen's unions in ports around the Fukushima Prefecture have voluntarily stopped fishing activities in sea areas off the Prefecture, though they were gradually resuming their business in the sea after the Fukushima Daiichi accident, taking time and measuring carefully doses of fishes they caught.
However, dose levels at some points, though not all the locations, recently measured in the seabed around the Fukushima Daiichi plant are several thousand becquerels per kilo gram of soil at most. It is not yet catastrophic though the allowable dose for fishes is 100 Bq/kg now in Japan.
